FIELD OF THE INVENTION

The present invention relates to roofing tools and accessories. In particular, the present invention is directed toward improvements in air powered roofing saws and other roofing accessories.

BACKGROUND OF THE INVENTION

Safety in pitched roof construction has been an ever increasing concern. An alarming number of construction site accidents are due to falls from pitched roofs by workmen, or injuries sustained by workmen when roofing materials (shingles, felt, nails, flashing, compounds, sealants, and the like) or tools (hammer, nail guns, water jugs, and the like) fall from a roof onto workers or passersby below.

One of the basic difficulties in roof work is transporting the materials up to the roof and storing them there until needed. Typically, roofers will load most, if not all, of the roofing materials onto the roof surface before beginning work. In the past, this may have been accomplished by the use of ladder elevators (e.g., laddervator). However, in new home and large scale construction, a crane or large forklift may be used to transfer entire pallets of roofing material to the roof level upon delivery. Thus, large quantities of shingles, tiles, slates, or the like, may need to be stored on the roof prior to installation.

In some recorded instances, entire pallets or “squares” of roofing materials (e.g., shingles) have fallen off pitched roofs onto the ground below. If a fellow workman or passerby is below when such a large amount of material falls, serious injury or even death can occur. In addition, although probably less hazardous, workers and passersby below are also in danger of serious injury from falling tools, hammers, and smaller amounts of roofing materials and the like. As a result of such accidents, residential as well as commercial roofers are finding increased scrutiny from insurance companies and government agencies (e.g., OSHA).

In addition to such obvious safety concerns, government agencies and insurance companies are seeing more claims of injuries due to repetitive stress disorders (e.g., carpal tunnel syndrome). In the roofing industry, such stresses can occur as a roofer may be forced to reach in one extreme direction (e.g., downward to a scaffold walkboard) to retrieve shingles, tools, or nails, and then reach in another extreme direction (e.g. upward) to secure the shingle to the roof.

In addition to causing stress on the body, such a work environment is inefficient, as such long reaches increase the time needed to install shingles and more readily fatigue the roofer. Moreover, extended reaches may put the roofer at increase risk of falling due to loss of balance and the like. Roofing materials and tools may be more likely to fall off a roof if a roofer has to stretch to reach them.

In the Prior Art, primitive techniques have been used in an attempt to secure materials and persons on a roof. For example, a short length of 2″ by 4″ wood may be nailed to a roof to provide temporary support for a ladder, materials, or a roofer. Such a primitive technique, commonly used, provides very little purchase for the roofer or materials to rest upon. In addition, it may take time at the jobsite for the roofer to secure such scrap lumber, cut it to size, measure for nail spacing, and install.

A number of patents have been issued which describe various apparatus in the Prior Art for correcting the deficiencies noted above. However, most, if not all, of these attempts have failed in one or more ways, and none of these patented invention appear to have been commercially successful or readily available in the marketplace. Most of these schemes utilize unnecessarily complicated apparatus, which is too costly for the average roofer to afford, to heavy to lift to the jobsite, and to cumbersome to work with.

For example, Eisenmenger, U.S. Pat. No. 5,601,154, issued Feb. 11, 1997, discloses a portable suspended roof scaffold system. Eisenmenger uses a specialized apparatus (See FIGS. 1, 3, and 4) to secure a ladder to a roof. Once the ladder is secured, an adjustable platform (See FIG. 7) may be secured to the ladder to support a walkboard or the like. The problem with the Eisenmenger system is that it requires that a ladder with specialized fittings first be hauled up to the roof and secured before the platform can be installed.

Moreover, the ladder, once secured, covers a substantial portion of the roof being worked on. Since shingles are generally installed in horizontal rows, the ladder of Eisenmenger necessarily covers a portion of each row at all times (See, FIG. 20). The roofer must either move the entire apparatus or try to install shingles underneath the ladder. In addition, the apparatus, by requiring the use of a ladder, ties up one of the roofer's ladders at the jobsite. As a result, the roofer must purchase a separate ladder for such a purpose, or do without a ladder at another location on the site.

Bitner, U.S. Pat. No. 5,979,600, issued Nov. 9, 1999, discloses a leveling roof platform support. The Bitner device is an improvement over using a nailed-in 2″ by 4″ and much less complex than the Eisenmenger device. However, it appears that Bitner is limited to a device for supporting a walk-board or plank, and does not explicitly provide support for ladders, tools, supplies, or roofing materials. In addition, the Bitner device utilizes a fairly complex and expensive screw-jack leveling system to provide infinite adjustment of angle. While the screw-jack system may provide more levels of adjustment, it does so at the expense of added cost and complexity. Moreover, the screw-jack of Bitner does not appear to be sufficient to support large loads (e.g., square of shingles). No method of locking the screw jack into place appears to be present.

Thus, it remains a requirement in the art to provide a simple, flexible, lightweight, safe, and inexpensive system for supporting persons, ladders, roofing supplies, shingles, tools, and accessories on an inclined roof without covering up large portions of the roof with such a device.

Miller, U.S. Pat. No. 6,170,222, issued Jan. 9, 2001, discloses a foam rubber wedge pad for placing shingles on a roof. As the pad is made entirely of foam rubber, it may be difficult to grip (no handles). Moreover, the foam pad does not provide storage for small items such as nails or tools.

In addition to the above problems in the Prior Art, injuries have occurred when ladders and scaffolding set up for roof and other work are not properly secured and as a result, fall down. OSHA requires that ladders be “tied-off” prior to work commencing. However, oftentimes a convenient and easy way to tie off a ladder (e.g., to a gutter) is not present, particularly with regard to roofing work.

Thus, it remains a further requirement in the art to provide a safe, easy, convenient, and inexpensive way to allow ladders and scaffolds to be readily attached to a housing or other structure prior to work commencing.

In addition, safety in transporting roofing and construction ladders, as well as other items is also important. An aluminum ladder flying off a construction truck can cause great bodily injury or even death on a crowded superhighway. Such dangers pose huge liabilities for construction companies, which may be ultimately responsible for the actions of their employees.

Moreover, securing any load to a vehicle present safety problems. Most commercial over-the road truckers have rather elaborate straps and chains to secure loads. However contractors and homeowners have relied upon straps, ropes and even strings, to secure loads to their vehicles, with limited success and sometimes disastrous results.

Many contractors will leave ladders entirely unsecured on ladder racks, or use only a token string or rope to secure them. In addition to being unsafe, ropes and strings are difficult to tie and untie. Straps (since or ratchet) are one solution, however, they are generally provided with large rubber hooks, which may slip on a ladder or luggage rack or may be difficult to secure.

Homeowners may attempt to use luggage racks supplied with their vehicles, or commercially available racks, such as the THULE® or YAKIMA® racks to secure objects to their vehicles. However, the YAKIMA® and THULE® racks may be highly specialized in their purposes and thus require an enormous amount of accessories in order to secure various items. Moreover, accessories for one rack (e.g., YAKIMA®, which uses round tubing) may not fit another rack (e.g., THULE®, which uses square tubing). Luggage racks supplied with cars generally are of little use and provide few or no places for tie-downs or the like.

When installing roofing materials, it is often necessary to cut shingles either before installation, or in situ. For example, when building a roof “Valley”, shingles may be installed over the valley, and then later cut to the valley “V” shape. Traditionally, a knife has been used for such cuts. However, there is little precision in depth of cut with a knife, and in addition, such a cut can be laborious and difficult. Too deep a cut may create roof leaks.

Power tools are generally not well suited to cutting shingles. Most are heavy and require electrical power. In addition, large power tools present a hazard to workers below if they fall off the roof. What is needed is a small powered tool which can cut shingles accurately and cleanly.

The apparatus may have particular use when ladders are used on roofs and uneven or inclined surfaces are present.

In another embodiment of the present invention, a lightweight adjustable ladder and scaffold support is provided which may be marketed under the name GABLEMASTER™, a trademark of the inventor. A pair of rails are provided, spaced approximately 24 inches apart (or adjustably spaced) to fit the standard spacing of most roof joists. Connected to the rails through suitable holes and slots, are rods supporting an adjustable platform. One of the rods may be placed through a corresponding slot to achieve a suitable angle of adjustment corresponding to roof incline.

The platform may be provided with a number of aluminum beams drilled with suitable holes, spaced apart and shaped so as to accept the leg of a standard extension ladder or siding jack. Bolts or pins may be passed through the holes to secure the ladder or jack to the platform. In addition, the platform may support a walking board, scaffold, or the like.

In another embodiment of the present invention, a bracket for holding a ladder on a sloped roof is provided. Ladder legs may be locked into the bracket using pins, bolts, or the like, such that the ladder will not fall off the sloped roof. This invention has particular application when a roofer needs to climb an existing roof to the peak when no safety rope, guide wire, scaffolding, or ladder is in place. The bracket may be nailed to the roof, a ladder slid up the roof and the bottom of the ladder secured to the ladder bracket.

In another embodiment of the present invention, a jack post roof rack holder is provided as a variation on one invention set forth in related Provisional U.S. Patent Application No. 60/297,530 filed on Jun. 13, 2001.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is a front view of the ShingleSaw™ Miterbox of one embodiment of the present invention. This miterbox may be used to cut shingles at a predetermined angle, or may be used to cut siding, particularly fiber cement siding that is becoming popular as a durable alternative to traditional siding products. Such fiber cement siding is hard to cut, and to date, no tool other than applicant's is really suited for such use.

Note the optional accumulator tank to provide sufficient air pressure and volume to the saw. The saw may comprise a ShingleSaw™ as developed by the inventor and as presently sold by ROOFMATES™ Inc., as well as improved versions of the ShingleSaw™ discussed below and also to be developed in the future.

A pair of rails in this embodiment allow the saw to slide back and forth to cut the material. Since the ShingleSaw™ generally uses small (3-4″) blades, a traditional pivoting power miter box construction may not be suitable. A dust bag may be provided to collect dust, particularly fiber cement dust which may be an inhalation hazard.

FIG. 2 is a side view of the ShingleSaw™ Miterbox of one embodiment of the present invention. Note that in this embodiment, a pivot-type miter-box action is used. This embodiment may be used with a larger blade, or may be suitable for cutting smaller pieces or the like.

FIG. 3 is another view of the ShingleSaw™ Miterbox of the present invention illustrating a rolling miterbox application for use on a walkboard for cutting siding and other long materials. In this embodiment, the entire miter box can be slid along a pair of rails mounted on the walkboard, allowing a siding man to cut fiber cement or other types of siding easily. The box may be rotated and reversed (e.g., 180 degrees) so that opposite pieces may be cut for a roof peak, for example, without having to reset the miter box constantly. The box can be slid from one end to the other and pieces cut with miters on both ends, for example, with the same cutting angle. FIG. 4 illustrates the table and walkboard brackets for the embodiment of FIG. 4.

FIG. 5 illustrates another embodiment of the ShingleSaw™ of the present invention. In this improved ShingleSaw™, a speed control and blade guard may be provided. An example of a blade design is also illustrated as a 5⅜″ diameter blade with carbide inserts. The following Figures illustrate other types of blade designs contemplated by the inventor.

FIG. 6 illustrates a chromalloy heat-treated 2-tip hook blade for use in the ShingleSaw™. FIG. 7 illustrates a chromalloy heat-treated 4-tip bi-directional star blade for use in the ShingleSaw™. FIG. 8 illustrates a chromalloy heat-treated 3-tip hook blade for use in the ShingleSaw™. FIG. 9 illustrates a chromalloy heat-treated 4-tip hook blade for use in the ShingleSaw™. FIG. 10 illustrates a heat-treated 3-tip blade for use in the ShingleSaw™.

FIG. 11 illustrates an AirKnife™ blade for mortar joints for use in cutting holes in fiber cement and for cutting mortar. This blade may be impregnated with diamond dust on the end to provide cutting action. FIG. 12 illustrates an AirKnife™ hook blade. Note that the AirKnife™ previously disclosed in applicant's co-pending applications, comprises a reciprocating air-powered device which may be used to cut shingles and the like.

FIG. 13 illustrates a chromalloy heat-treated 4-tip blade for use in the ShingleSaw™. FIG. 14 illustrates a 3-tip summer blade with carbide inserts for use in the ShingleSaw™. this summer blade compensates for the higher temperatures in the summer and should reduce the tendency of many roofing materials to stick to the saw blades. Teflon or the like may be used to coat the non-cutting parts of the blade.

FIG. 15 illustrates a fiber cement blade with carbide inserts and impregnated with diamond dust for use in the ShingleSaw™ and ShingleSaw™ Miterbox. FIG. 16 illustrates a fiber cement blade with carbide inserts, a “raked” profile, and impregnated with diamond dust for use in the ShingleSaw™ and ShingleSaw™ Miterbox. Note how the “raked” profile is used to reduce the tendency of the blade to stick to the material being cut.

FIG. 17 illustrates an improved pole bracket for securing a pump jack pole. This simplified version of the pole bracket is lighter and less expensive than previous versions.

FIG. 18 illustrates a side view of an improved embodiment of the GABLEMASTER™ of the present invention which is discussed in more detail below in connection with the APPENDIX of the present application.

FIG. 19 illustrates one embodiment of a COOLING HARD HAT. FIG. 20 illustrates another embodiment of a COOLING HARD HAT. In these embodiments, one or more battery operated fans may be driven by a belt-mounted battery and/or hat mounted solar panel to provide cooling to a heard hat wearer.

FIG. 21 illustrates the TRASH-CATCHER™ device which may be placed on a gutter to prevent debris from entering the gutter or falling over the side of a roof. A padded rail may lock the device to a gutter edge without marring the gutter. The device covers the gutter and prevents nails and roofing detritus from entering the gutter. Multiple devices may be installed to cover larger areas of gutter. The device may also be used to prevent roofing detritus from falling on persons below or cluttering the ground below.

The Attached APPENDIX illustrates another embodiment of applicant's AIR STATION™, a product designed to hold compressed air and/or act as an air accumulator. Compressors used by roofing contractors generally do not have a high capacity, as most air powered roofing tools, such as nailers, are used intermittently and do not require high volumes of air.

With the introduction of new tools, such as applicant's ShingleSaw™ additional air capacity may be needed. However, even such high air requirement tools such as the ShingleSaw™ may be used only intermittently. Moreover, roofers will be loath to spend money on a new larger compressor which is expensive and heavy. The AIR STATION™ tank can be used to store compressed air which may then be used on a roof. Alternately, it may act as an air accumulator, such that sufficient air pressure and volume is available for the ShingleSaw™ or other tool.

Note the foam padding on the bottom of the device to prevent it from slipping off a roof. An air inlet (quick connect) may be provided to connect the device to a standard compressor. Multiple air outlets may be provided to allow multiple tools to be connected to the device so that a roofer does not have to switch air lines between tools—an awkward and time consuming process. In addition, the multiple outlet ports allows multiple roofers to have access to air pressure at the same time. A carrying strap may be used to allow the device to be easily carried. The storage tank or tanks may comprise standard steel or aluminum tanks or the like, or may be made from PVC pipe. A pressure gauge (not shown) may be added to indicate air pressure.

The APPENDIX also contains a plan drawing for an improved version of the GABLEMASTER™. This version is smaller in size and provides bracketing to hold a pump jack pole (center) or a ladder in one of two orientations (side pockets). The smaller size of this unit and lightweight construction make the device easier to carry and lift to the roof.

While the preferred embodiment and various alternative embodiments of the invention have been disclosed and described in detail herein, it may be apparent to those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope thereof. 

1. A air powered miter box for cutting construction materials, comprising: an air-powered saw having an inlet for accepting compressed air and a rotary air motor for rotating a rotary saw blade, mounting means for slidably mounting the air powered saw so that the air power saw may be adjusted for angle of cut and also slid in a cutting direction of the rotary saw blade, and a material holding platform, for holding construction material to be cut and maintaining a predetermined angle between the rotary saw blade and the construction material to be cut.
 2. The air powered miter box of claim 1, wherein the material holding platform further comprises: a support structure for attaching to a scaffolding for holding long lengths of construction materials for cutting.
